Looking for Islandora Disk Configurations

[Mark McFate]

Can anyone suggest where I might find information about different Linux disk configurations/strategies that work with Islandora?  Is it possible, for example, to put the code on one filesystem and save the Fedora objects on another?

Hi,

We have deployed a 2 servers solution for Islandora and Fedora Commons, with virtual machines and remote storage on a cluster partition.
You can found everything here http://dev.digibess.it for Drupal6 and first setup here http://devbioinfo.to.cnr.it for Drupal7.
For Fedora Commons and Solr we have changed default partition for objects and index to remote cluster partition (iSCSI mounted as folder).

Best,
Giancarlo

Thank you Giancarlo. 

I am talking with our IT folks about building a similar 2-server configuration.  I'm wondering, is there any drawback to using iSCSI...speed, performance, etc?   I understand you are supporting a distributed collection, correct?  In that mode I can clearly see the need/benefit of iSCSI.  I'm wondering if we should deploy the same even though we do not have distributed data, yet?

Hi Mark,

the problem was the storage for repository objects (>15TB / high availability /open source) and we solved it by a two node active/passive cluster in HA. We tested several network protocols and iSCSi was the best solution for connection between repository and the SAN in our case.
I think you can start deployment of your prototype without SAN, you can use local storage of server.
You will need SAN before start production ingesting of objects because I think migration from local storage to network storage of a lot of data is very hard.
I hope this answers your questions,

Giancarlo
